Mm or, “mommy milkers” is a way to describe women’s breast in a sexual manner. This slang is usually used thirsty 12 year old boys on the internet. This slang originated from a popular app named “tiktok.” It was also used commonly in a popular game called “roblox” where little kids used to “role play” in games such as “life in paradise.”
